Keeper of the Gates of the Moon

Keeper of the Gates of the Moon is a title originally held by a noble charged with holding the Gates of the Moon, the winter seat of House Arryn. The post was usually granted to kinsmen of House Arryn and it was never hereditary,[1] as the Arryns themselves had raised the Gates when they ruled as Kings of Mountain and Vale,[2] prior to the construction of the Eyrie.[3]
